GDK groovydocs for String.padXXX are not very clear [new wording attached]

I was trying to work out what padLeft etc did from the docs, its not very clear:

"Pad a String with the characters appended to the left"

The argument "numberOfCharacters" does not give you the clue that this is the target width.

I would suggest therefore a change in working in this and related methods:

"Pad a String to a minimum length specified by numberOfCharacters, with padding characters added to the left."
